DQ: How do we define features on a contour map?
• Anchor: Answer question based on this map.
How do we analyze a contour map?
Contour Lines Rules
• 1) All points along any given contour line represent the same elevation
• 2) Contour lines never touch or cross • 3) The spacing between contour lines help us determine the
slope. • 4) When contour lines cross a stream or a river they are V
shaped.
19) Index Contour: A darkened contour line used to represent a specific elevation. It help us determine elevation at certain points more quickly. Index contour are evenly spaced for example: every 100 feet or every 200 feet.
How can we predict the contour interval?
How do we add directions to contour map?
How can we read special features on a contour map?
Contour Rules• Rivers bend up stream.

Depressions • Depressions represent an area where the land
dips inward.

• 3) A ski lodge where people can see the sun set• 4) A river which flows down the mountain • 5) A depression any where on your mountain.
